OzinWe investigate the temperature and power dependence of the emission quantum yield of NaYF4:Er,Yb upconverters. We demonstrate that formation of the hexagonal phase of this material is not in itself sufficient to guarantee high upconversion efficiencyThe content of this RSS Feed (c) The Royal Society of Chemistry
